Microscale Vacuum Apparatus with Hand Pump
Product Code : SCL-CL-11878
Microscale Vacuum Apparatus with Hand Pump (SKU SCL-CL-11878) is a small bell jar, 10 cm high and 5 cm in diameter, evacuated with a hand pump so that each student group can explore low pressure at its own lab station. Rather than watching a single demonstration, learners run the experiments themselves. It suits middle-school science and Class 9–11 physics and chemistry, and is quoted by Science Lab Supplies from Ambala, India for schools, colleges, training institutes, distributors and tender contractors.
Specifications
Dimensions and parts of the microscale bell jar set are listed one per row in the table. In short, the jar measures 10 cm in height and 5 cm in diameter for use at a student station, and pumping air out by hand lowers the pressure inside so objects and liquids placed in the jar react visibly.

Applications and Experiments for the Microscale Vacuum Apparatus
Reducing the pressure around an object shows students how much work the atmosphere normally does. With this apparatus a balloon swells, warm water boils without heating, and liquid can be moved between pipets. It supports air-pressure topics in NCERT Class 8 science and states of matter in Class 9 and 11.
- Class 8: air exerts pressure, shown by a small balloon expanding as the jar is pumped.
- Class 9 and 11: boiling point falls with pressure, shown with warm water; compression can be contrasted on the Manometer Cylinder with Piston Temperature Meter.
- Volume change of foams, such as a marshmallow or shaving cream, as pressure drops.
- Transferring liquid from one pipet to another using pressure difference, with 0.5, 1 and 5 ml Calibrated Plastic Droppers available on the same quotation.
Use only warm, not hot, water, and let air back in slowly before lifting the jar.
Standard Scope of Supply
Each set comprises the microscale bell jar, 10 cm high and 5 cm in diameter, and the hand pump. Balloons, pipets, marshmallows and other test materials are separate; any of them, or other optional accessories you request, can be listed on the quotation alongside the set.
Packing, MOQ and Lead Time
The apparatus is designed for student stations, so it can be quoted one per group or as a single set. The quotation covers packing, delivery time and price for your number, and other school chemistry lab equipment in India can be added to the same document.
Science Lab Supplies holds an Importer-Exporter Code and can ship to buyers in Egypt, Iraq, Nigeria, Kenya, Ghana and Ethiopia. Prices for one set or a class quantity can be requested from the contact page or by building a list in the enquiry cart; tender procedure is explained on the lab tender page.
Frequently Asked Questions
How big is the bell jar?
It is 10 cm high and 5 cm in diameter, a microscale size meant for a student lab station rather than a large demonstration jar on the teacher's bench.
What experiments can students do with it?
Expanding a balloon, boiling warm water at reduced pressure, watching a marshmallow or shaving cream grow, and moving liquid from one pipet to another by pressure difference.
Who supplies the Microscale Vacuum Apparatus with Hand Pump?
Quotations and dispatch are handled by Science Lab Supplies in Ambala, India, for schools, colleges, training institutes, distributors and tender contractors ordering one set or several.
Does it need electricity?
No. The vacuum is produced with the hand pump, so the apparatus can be used at student stations in classrooms that have no bench power supply.
